This invention relates to a combined gas cock and lighter, the general object of the invention being to provide means whereby the flow of gas to the pilot burner is increased 8 when the'cock is turned on to supply gas to the burner, so that the increased flame of the pilot light 'will ignite the gas at the main burner. 1 H

Another object of the invention is to so construct and arrange the'parts that the valve which .controls the supply of gas to the pilot will be opened when the cock is being moved to open position and when the cock reaches fully open position, the pilot valve will be closed and will'remain closed when the cock is being closed.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to so be hereinafter'fully described, illustrated in the accompanying drawing and specifically,

pointed out in the appended claims.

In describing the invention'in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view through the device. 4

Figure 2 is a plan view.

Figure 3 is a sectional view through the pilot valve assembly, with the valveclosed.

Figure his a sectional view throughthe lower part of the ilot valve assembly, showin the slot in which theball is placed.

11 these views, the numeral 1 indicates the casing of the main cock 2, thiscasmg bemgprovided with the usual inlet 3. and outlet 4. The casing is provided with an enlargement 5 at one side thereof forming a chamber 6 which'is divided into upper and lower portions by the valve seat 7. The upper portion is connected with the inlet 3 by t e' passage 8 so that said upper portion of the chamber is always in communication with the supply.

A spring pressed ball valve 9 is arranged in I the upper portion of the chamber and is normally held upon the seat 7 by its spring."

An opening 10 is arranged in one side of the enlargement and has a portion of its .flow of gas to the pilot will be cut oil and inner end communicating with the upper art of the chamber above'the valve seat an its lowerportion communicating with the lower part of the chamber below the valve seat so as to form a by-pass around the seat. A hand operated valve 11 is threaded in the opening and has its reduced lower end controlling the lower part of the by-pass so as to regulate the amount of gas passing from the upper part of the chamber into the lower part thereof. I

The pilot tube 12 is connected with the lower part of the chamber and has the usual tip 13 on its outer end. i

A rod 14 passes through a gland 15 in the lower part of the enlargement 5 with its upper end engaging the valve 9 and its lower end is formed with an enlargement 16 which is formed with a slot 17 therein to receive a ball 18. An arm 19, is connected with the lower end of the cock 2 and thesepart-sare so arranged that when the cock is being moved to open position, the arm will strike the ball 18 and as said ball is in engagement with the I end wall 17 of the slot, the ball is prevented from movement in the slot so that the arm will raise the rod 14 and thus force the valve.

9 01f its seatso that a considerable quantity of gas can pass from the upper chamber into the lower chamber and thus flow into the 'pilot tube and increase the flame at the tip so that the gas at the main'burner will be ignited. When the cock has been moved to v its fully open position, the arm will have 1 passed'under the ball so that the rod 14 can drop to itslowest position and the spring will 95 close the valve 9, so that but a small amount of gas will pass to the pilot burner. When the cock is moved to closed position, the arm will strike the ball 18 from an opposite .direction so that the ball will simply be pushed up the slot 17 and no movement of the rod 14 will take place.

Thus I have provided simple means for supplying an increased amount of gas to the pilot burner when the main cock is being opened to supply gas to the main burner. Thus the large flame at the pilot will ignite the gas at the main burner. When the .cock

reaches its fully open position, the increased 0 al-1kg.

when the cock is moved to closed position, no action of the valve of the pilot will take place.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is r 1. A combined gas cock and lighter comprising a casing, a main cock therein, a chamber formed in the casing, a valve seat in the casing dividing the chamber into two parts, a pilot burner connected with the lower part, a spring pressed valve in the upper part for engaging the seat, means for connecting the upper part with the gas supply, a by-pass for connecting the lower part with the upper part, a rod extending through the bottom of the lower part and having its upper end on lgaging the valve, the lower part of the rod aving an enlargement thereon provided with an'inclined slot, a ball. in the slot and an arm on the lower end of the cock which will engage the ball on the opening movement of the cock and thus raise the rod to push the valve oil its seat, after which the arm passes riding up the slot when engaged by the arm from under the ball, said ball riding up the slot when en aged by the arm on the closing movement 0 the cock.

2. A combined gas cock and lighter comprising a casing, a main cock therein, a chamber formed in the casing, a valve seat in the casing dividing the chamber into upper and lower parts, a pilot burner connected with the lowerpart, a spring pressed valve in the upper part for engaging the seat, means for connecting the upper part with the gas supply, a by-pass for connecting the lower part with the upper part, a rod extending through the bottom of the lower part and having ts upper end engaging the valve, the lower part of the rod having an enlargement thereon provided with an inclined slot, a ball in the slot, an arm on the lower end of the cock which will on age the ball on the opening movement of t e cock and thus-raise the rod to' push the valve off its seat, after which the arm passes from under the ball, said ball on the closing movement of the cock and means for adjusting the size of the by-pass.

In testimony whereof I aflix my signature.
